BEACON voltage

 

Good afternoon.

We are trying  to ping test beacon pn 266-e5542-00.  Falcon airframe work card does not give the acceptable voltage on the end terminal.

Can yougive us some guidance?

Todd

Good morning, Todd,

The battery Min Acceptable voltage is 2.97V.

F900ex Weighing

There was a little controversy on weighing, here is how it played out:

 

 

 

here is the math

 

716BH WB calculation

 

 

We have positively identified the correct nose arm for the F900/F900ex series.
The previous numbers are incorrect, as it refers to gear retracted.arm.
The confirmation came in the Loading Manual drawing , attached to this email.
Could you please change the nose arm to -287.57 on both reports and recalculate.
Also could you add these notes to your reports:

F900EX Generator traumas

This is an old presentation i set up.

I thinkmi cabbaged some stuff from flcon, and added some art.

Old notes:

Old troubleshooting notes on a long-legged problem: engines running:

  1.  Check for Bleed leak blowing on GCU.  BE very carefull if you elect to run the AI on the ground.  !!!!!!APU BLEED OFF!!!!!!, slats extended.    20 seconds ground test max. leave the slats out to cool.
  2.  Test “E” ground quality.  Fluke on volts.  Black lead to airframe ground, red lead to GCU Black test point.  Very small voltage~ .1v.  less is better
  3. Volt drop on line contractor.  Fluke meter on volts.  Red lead on upper contactor, bottom big bolt, black lead on same contactor, upper big bolt. Very small voltage~ .1v.  less is better.
  4. Ripple test.  use fluke MIN/MAX.

Run each test with only 1 gen online, 50 to 100 amps load, try to hold conditions quite similar for each test.

some other thoughts:
look at big E terminal, small 20awg terminal.

double check each  GCU voltage. Is it stable at 28.5? is it stable with load? is it stable with RPM change?

select cockpit red switch to off.  Is the voltage of a running generator, cockpit switch selected off,  .7v to 1.0v at idle? this checks the quality of the permanent magnets inside the Generator.

ASSURE that NO ENGINE GENERATOR  has a cooling fan installed. (possibly a borescope through the black sooty outlet.) or it mat be necessary to unbolt the cooling exhaust.

Initial problem definition:

#3 Gen Light occasionally, Much troubleshooting. Gen 3 amps tend toward zero. #1 seems to “take the load”

 

History:

#3 gen troubleshooting, #1, #3 gen shunts…..?Removed?
